[osg-users] render to texture only delivers black texture
Hi everyone. I have some issues with rendering to a texture. I am writing a plug-in for an application. This application has a main-viewer-window, where it displays a scene. My plug-in has an own window with a new viewer and everything. The new window now needs a texture showing what the main window displays right at this moment. I need it to use it later on with an API for interlacing but for now I just want to show it in the plug-in-window to see whether rendering-to-texture works as it should. That is why the plug-in-window show a screen-aligned-quad that displays this texture. If I use an image as texture of the quad everything works as it should, so my plug-in-window should be fine the way it is. But if I use the texture I render using a camera in the main application's scene I just get a black texture. I create the following camera using information of the camera of the main application which I get via an interface named _billInterface and attach the texture: osg::Camera* camera = new osg::CameraNode(); camera-setCullingActive(false); camera-setClearColor(osg::Vec4(1.0f,1.0f,1.0f,1.0f)); camera-setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Set camera properties according to the main camera of the main application osg::Camera* billCamera = _billInterface-getCamera(); camera-setViewport(0,0,_billInterface-getGraphicsContext()-getTraits()-width,_billInterface-getGraphicsContext()-getTraits()-height); camera-setProjectionMatrix(billCamera-getProjectionMatrix()); camera-setViewMatrix(billCamera-getViewMatrix()); camera-setReferenceFrame(billCamera-getReferenceFrame()); camera-setStateSet(billCamera-getStateSet()); camera-setRenderOrder(osg::CameraNode::PRE_RENDER,1); camera-setRenderTargetImplementation(osg::CameraNode::FRAME_BUFFER_OBJECT); camera-attach(osg::CameraNode::COLOR_BUFFER, texture.get()); Then I add the scene of the main application to the camera so that it shows this scene. camera-addChild(_billInterface-getScene()); Now I take this camera and put it into the scene graph of the main application: _billInterface-getRootNode()-getParent(0)-addChild(camera); (That way it is on one depth with the rootNode of the scene and the node containing the HUD. I put it in there so that the camera's output is rendered into the texture everytime the viewer of the main application is updated.) I know that I get a texture that way because the quad that holds this texture is normally red and after creating the camera and attaching the texture it turns black. I guess that either some camera properties are wrong or I have to put the camera somewhere else. Can someone give me a hint on what I might be doing wrong? What are the main things I have to take care of when doing render-to-texture? Is the texture automatically updated everytime the scene containing my render-to-texture-camera is rendered?

Yes, Geometry::setTexCoordArray(unsigned int unit,Array*) is *exactly* for multi-texture coordinates (one array per texture unit). They are fed to glMultiTexCoord internally. Unless you're looking for something else entirely? As was already mentioned, it doesn't work with ShapeDrawables.

Re: [osg-users] osgText background
I've done something like that. Each time I change the text, I recompute the geometry (quad) based on the Text's Drawable getBound(). It works for plane aligned text (xy, xz or yz). If you want to do that for screen aligned text, you'll probably have to look osgText code to have the exact size of the Text in screen coordinates. I would not use a billboard in your case, since you'll find difficult to have a billboard with a center of rotation that match with your text (especially if the text is dynamic). Try of quad in a HUD, with screen coordinates extracted from your text, and something smart with z-buffer parameters to have your text over your quad :) Luc Luc FRAUCIEL - BRGM Unité Calcul, 3D et réalité virtuelle Service Systèmes et Technologies de l'Information 3, av C.

Re: [osg-users] The growing draw bar in the stats handler
The short bars are probably the initial state of the bars that haven't been initialized yet. As for your single really long bar, this suggests that the GPU is stalled doing something for a very long time... It could possibly be a bug in the stats collection. The stats collection has been working fine for a year now, so I don't think there is a problem on the OSG side, but perhaps you've uncovered a bug in the driver. Robert.

Re: [osg-users] render to texture only delivers black texture
Hi Steffen, I'm finding it hard to follow exactly what your set up is. Since I'm not clear the best I can do is have an educated guess.

Re: [osg-users] osgviewerQT, qt4.4.0 and .osg file
Hi John, Great, a pictures saves a thousand words! The problem looks the same as others have encountered when WxWidgets modifies the C local such that atof switches from treating . and , as decimal points. My guess the later version of Qt is doing the same. We've tried several different attempts in the past to insulate the OSG from this change in local but weren't able to come up with a workable solution. The conclusion back then was that we might would need to use a custom atof method, this hasn't been developed yet though. Robert.

The problem looks the same as others have encountered when WxWidgets modifies the C local such that atof switches from treating . and , as decimal points. My guess the later version of Qt is doing the same. We've tried several different attempts in the past to insulate the OSG from this change in local but weren't able to come up with a workable solution. The conclusion back then was that we might would need to use a custom atof method, this hasn't been developed yet though. Robert.

Re: [osg-users] The growing draw bar in the stats handler
Hi Rick and Robert, I mentioned this problem few months ago. Happened on Windows XP and Vista. It seemed to dissapear with more recent NVidia drivers though (ver 169.xx and larger). I don't remember exactly but I think it was present only on dual monitors. Do you by any chance have dual view config ? Cheers, Wojtek Lewandowski The short bars are probably the initial state of the bars that haven't been initialized yet. As for your single really long bar, this suggests that the GPU is stalled doing something for a very long time... It could possibly be a bug in the stats collection. The stats collection has been working fine for a year now, so I don't think there is a problem on the OSG side, but perhaps you've uncovered a bug in the driver. Robert.

Re: [osg-users] Fog problem
Hi,
Ok, osgprecipitation lz.osg works.
So, I looked into the code and see it set the attribute and mode with the
osg::Fog from the precipitation instead of just enable the GL_FOG mode and let
the precipitationEffect do its work itself.
I correct my program and it run yet! Thanks a lot Robert!
Now, I think it is normal to obtain undefined result if I enable fog without
set the other attributes... But I still ask me why it worked until yesterday,
since I introduced precipitation two weeks ago!

Re: [osg-users] Fog problem
Now, I think it is normal to obtain undefined result if I enable fog without set the other attributes... If you enable fog, behavior is defined. In OpenGL, the defaults are: FOG_MODE is EXP FOG_DENSITY is 1.0 FOG_COLOR is 0,0,0,0 FOG_COORDINATE_SOURCE is FRAGMENT_DEPTH I don't believe OSG changes any of these, so this should be what an OSG app gets by simply enabling Fog. But I still ask me why it worked until yesterday, since I introduced precipitation two weeks ago! Something else in the code must have changed. It sounds like your app (or some library that it uses) used to set the FOG_MODE to LINEAR, but that code got deleted or changed and you suddenly got EXP instead, resulting in all black.

[osg-users] When optimizing with LOD changes, should I change UV map resolutions?
Hello All, I have been trying to get my scenes to run faster, balancing my scene graphs using LOD. I use quite a bit of UV mapping in my models, and they can be fairly high res because I want them to look good up close. There are usually several instances of the same model in the scene, all pointing to the same scene graph. I was wondering about the best way to create LOD changes for them. I was going to cut out some polygons, but I was also thinking of cutting the resolution back on the UV maps. Is this valuable? On first assessment, it seems it would be, but then I realize that it might cause MORE of a memory usage, and the graphics card (or OSG) might be doing this kind of optimization anyway (dropping image map resolutions based on pixel size or whatever). What are your recommendations? -- Thanks for everything Rick Check us out at http://fringe-online.com/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] MFC Fullscreen With Multiple Monitors

Subject: [osg-users] MFC Fullscreen With Multiple Monitors
I'm having a problem with inheriting window data from an MFC window in
OSG 2.2.
When I run an application with a dual monitor display the application
runs and OSG starts but it starts in fullscreen mode rather than
inheriting the MFC window size and location.
When I run the same application on the same machine but with only a
single monitor the OSG inherits the MFC window correctly.
Is there something that I'm missing?
Here is the code I use to create the window (borrowed from the MFC
viewer example):
// Local Variable to hold window size data
RECT rect;
// Create the viewer for this window
mViewer = new osgViewer::Viewer();
Add a Stats Handler to the viewer
mViewer-addEventHandler(new osgViewer::StatsHandler);
Get the current window size
::GetWindowRect(m_hWnd, rect);
Init the GraphicsContext Traits
osg::ref_ptrosg::GraphicsContext::Traits traits = new
osg::GraphicsContext::Traits;
Init the Windata Variable that holds the handle for the
Window to display OSG in.
osg::ref_ptrosg::Referenced windata = new
osgViewer::GraphicsWindowWin32::WindowData(m_hWnd);
// Setup the traits parameters
traits-x = 0;
traits-y = 0;
traits-width = rect.right - rect.left;
traits-height = rect.bottom - rect.top;
traits-windowDecoration = false;
traits-doubleBuffer = true;
traits-sharedContext = 0;
traits-setInheritedWindowPixelFormat = true;
traits-inheritedWindowData = windata;
// Create the Graphics Context
osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
// Init a new Camera (Master for this View)
_camera = new osg::Camera;
// Assign Graphics Context to the Camera
_camera-setGraphicsContext(gc);
// Set the viewport for the Camera
_camera-setViewport(new osg::Viewport(traits-x, traits-y,
traits-width, traits-height));
// Add the Camera to the Viewer
mViewer-addSlave(_camera.get());
// Add the Camera Manipulator to the Viewer
//mViewer-setCameraManipulator(keyswitchManipulator.get());
// Set the Scene Data
mViewer-setSceneData(mRoot.get());
// Realize the Viewer
//mViewer-getCamera()-setViewport(traits-x, traits-y,
traits-width, traits-height);
mViewer-realize();

Do you by any chance have dual view config ? Cheers, Wojtek Lewandowski The short bars are probably the initial state of the bars that haven't been initialized yet. As for your single really long bar, this suggests that the GPU is stalled doing something for a very long time... It could possibly be a bug in the stats collection.

Re: [osg-users] VPB generating terrain for multiple data files
Hi J-S, A third option might be to modify osgdem so it allows for non zero default elevation. However, even this is a bit of stop gap. Ideally should have data throughout your model to define all the heights you require, if you have holes then all you can come if with is an acceptable fudge for what this missing data might be. Perhaps the easist way to provide this fudge would be to create a single dummy DEM that covers the entire region and matches the elevations of the tiles you have. The actual data would then act is a high res inserts to this base level DEM. Robert.

So the terrain database looks like: (data)(no data)(data) ___Z = 0 | | | | __| |_ Z = -365 (viewed from the side) Are there any ways to fix this? I can think of two off the top of my head: * Translate all the terrain heights up by about 365 meters, so that everything is near Z=0, then generate the terrain, and at run-time translate it back down by 365 meters. * Use a fake tile of data that would encompass the whole terrain and would be at about -365 meters everywhere, and then the three data files I have would be additional data (higher-res overlays, as I have seen used in some terrain database). Are there any other options? I think the second option is better, but I would appreciate others' points of view on this.

Re: [osg-users] When optimizing with LOD changes, should I change UV map resolutions?
Hi Rick, The most efficient LOD's will be the ones created by specialist tools, or even a decent modeller. The aim of the lower level of details subgraphs would be to represent the subgraph with less of everything - less nodes, less separate state, less geometry, smaller textures, simpler shaders etc. The ideal would be collapsing down to a single osg::Geode/osg::Geometry and with a single osg::StateSet and a single Texture.Using a texture atlas is a good way to collapse separate textures down into a single texture. osgUtil::Optimizer has a texture atas builder that could help with this.

Re: [osg-users] VPB generating terrain for multiple data files
Hi Robert, Ideally should have data throughout your model to define all the heights you require, if you have holes then all you can come if with is an acceptable fudge for what this missing data might be. I know, I know... :-) I work with what our client provided, so I have to fill in the gaps myself. Perhaps the easist way to provide this fudge would be to create a single dummy DEM that covers the entire region and matches the elevations of the tiles you have. The actual data would then act is a high res inserts to this base level DEM. Yes, that was the second option I mentioned. Any hints as to how to do that? I have the FWTools distribution, which includes all gdal binaries, but if there's another tool that I could use, please point me in the right direction. Ideally, I would like the base terrain to conform to the inserts at the edges of said inserts, instead of having steps around the inserts... So the tool used would probably need to interpolate between the tiles. I tried using gdal_merge.py, currently waiting for the terrain to generate from the result of that (I can't use --TERRAIN, so it takes a while)... But it doesn't interpolate, it just puts either NODATA or a value you specify. Anyways, thanks for confirming my intuition.

Re: [osg-users] When optimizing with LOD changes, should I change UV map resolutions?
Robert's comment regarding texture atlas usage in low-res LOD children is an excellent suggestion. Going further, your post begs the question: Do you suspect that texture memory usage is the bottleneck to your performance? One way to test this (if you haven't already done so) is to set the OSG environment variable to limit the maximum texture dimension to something ridiculously small. If your app runs faster with this setting, then texture memory usage might be causing performance problems, and you might need to address that in some way. You should keep in mind that most OpenGL device drivers are smart enough to page out large mipmap levels when they are not in use. Another thing to keep in mind is that a texture never needs to be larger than its max representation on-screen. For example, it's pointless to have a 2kx2k texture applied to an object that will never subtend more than 500x500 pixels. Hope that helps. -Paul _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, July 10, 2008 7:09 AM To: OpenSceneGraph Users Subject: [osg-users] When optimizing with LOD changes,should I change UV map resolutions?

Re: [osg-users] Weird driver problems?
Hi J-S,
It looks bit like the issue I strrugled with. I am not sure if my
workaround - repeating makeCurrent - was added before 2.4 release or after
it. Certainly 2.2 is not safe.
You may check if bool GraphicsWindowWin32::makeCurrentImplementation() looks
like this:

if (!_realized)
{

Hello,
We've started seeing something weird on some of our machines, and I'd
just like to know if someone else has seen this. These issues started
happening today.
Setup: Windows XP, GeForce 7800 GTX and 8800 GT, OSG 2.2 and 2.4, two

The weird thing: switching from Dual View mode to Horizontal Span mode
fixes both these issues.
Our current theory is that some automatic windows update that got

Hi Peter, You can achieve a multitexture effect quite easily again look at my tutorials. The problem is all about defining the geometry of objects yourself and in order to do this you will need to rely on the geometry class.

Hello Brian, It may be a far jump but my thoughts are this leads us down the path that it there is possibly something either in the osg plugin or more likely - the 3d functionality and the extra logic and threads needed to accomplish the 3d display. You seem to think that osgviewer with or without --image does radically different things... It doesn't. It's the same viewer, the same setup. It will detect and use the same thread config, etc. When you do osgviewer --image bob.jpg it creates a quad (in 3D space) and maps your image onto it as a texture. So it's still displaying a model in 3D. Yes, it may be the .osg loader, but it may be something totally unrelated.

Re: [osg-users] RE : Re: RE : multitexturing coordinates
Hello Franclin, But for shape drawable, geometry information is hidden to clients (and I don't know why but I suspect performance issues) that is why you need to use shaders for them. Well actually the Shape / ShapeDrawable classes were originally designed as simple debugging tools, so little thought was put into their design. They're just implemented as simple display lists with little customization possible, and no access to the internals. If you want to do any serious geometry with any acceptable level of control, you'll want to use osg::Geometry and define the vertices yourself. One side of the coin: --- I had suggested to Robert that I could reimplement the Shape / ShapeDrawable classes using an underlying osg::Geometry, so that they would behave as they do now but offer more control if needed (probably as it should have been done right from the beginning). He was open to this, but I haven't had time to do it yet. The other side of the coin: - Do you know how easy it is to download Blender, create a sphere, save it and load it up with OSG? And when you do, it will be a full-fledged osg::Geometry and you will have total control over it. If you use the osg exporter for Blender you can even edit the .osg file and make sure it's structured exactly how you want it. I generally favor using data for everything (as much as possible / reasonable) as opposed to hard-coding things, since later it's much easier to replace the sphere model by something else if it's a model file than if I have to open the project, find the relevant code, change it, compile it, test it... This is just my opinion though, and the Shape / ShapeDrawable classes still have uses, which is why I still want to do what I mentioned above, someday. :-) Hope this clears things up.

Thanks for response... I'll look into that... but first there is a bigger problem with osgviewer.
